    Some operators also have a tertiary bitumen recovery circuit, where bitumen is recovered from the tailings (underflow) of the main gravity separation vessel. As in the case of middlings recovery, bitumen is recovered using a series of flotation cells. This low quality froth is recycled back to the main gravity separation vessel for final clean up.
